The present invention relates to the production of compounded oils in general, and more particularly to the class of oils know-n as cutting oils. Tm ortant objects of this in- 5 vention are to pro uce a superior quality of cutting oil and to providean improved process for the production of such oil.

- According to a specific example of thepresent invention, the compounded oil is produced by introducing flowers of sulphur nto lard oil and thereafter combining the resultant product witha mineral or paraflin oil. i In carrying out the rocess, one may proceed as follows: 10 ga ons of a fat oil such as lard oil are heated to a temperature in the neighborhood of from 450 F. to 475? oil being thoroughly agitated during the heating operation to obtain uniform heat- ,ing ,throughout. The application, of heat is then discontinued and twenty 1 pounds of finely divided flowers of 'sul hur are very carefully stirred into the fat 011. A foaming ,will shortlycommenceand this foamingis allowed to proceed fora few minutes after.

which a small amount of paraflin oil (for example 1 to 2 gallons of arafiin oil of a viscosity in the neighborhoo of 100 seconds at 100 F. Saybolt standard) is slow added while stirring. This additionof t p will cause, the foaming or reactiontov subside. The stirring of the oil-is still continued and shortly a second foaming will start,.which In the process of compounding cutting 80 is allowed to progress until it subsides of its own accord and then from 3 to of the paraffin oil above referred to is carefully 4 while continuing the stirring After all aet 'tion has subsided, the mixture is 'dilute'dwith theup'araflin oil in further quantity, as above, 4 an a-total desired volume of,- for example,-

Compounded lubricating oil produced according to the present process contains a high proportion of sulphur and exhibits superior properties or qualities as a cutting oil.

It will be understood that the above example which has been specifically given is'intended only as an illustration of the principles involved in the invention, and that modifieations' may be adopted within the principle illustrated: to conform with special requirements, wit out departing from the spirit of' i the invention.

What is claimed. is I 1. The process of compounding cutting oil, which comprises heating a lard oil to a tem perature in'the neighborhood of from 450 F. to 47 5. F., while thoroughly agitating the .the heatin and introvducing finely divi ed flowers o sulphurv in the proportion of approximately 20 poundsof sulphur, to 10 gallons of lard oil with thorough a "tation, allowing the-resultingaction to contmue for a few minutes andthereafter 7 0 adding paraflin oil of a viscosity in the neighv at 100 F. Saybolt standard until 4 to 7 gallons of paraflin oil are added to each 10 gal ons of lard 'oil,' continuing to stir the mi [tu're while the reaction proceeds, and after all action has subsided diluting the. material with a further quantity of f I oil, the steps which comprise heat ng agitating lard oil at a temperature in the neighborhood of from 450 F; to 475 F;, dis.- continuing the application of heat, and intro- .ducing "finely divided flovs'rers of sulphur into the hot lard oil in the pro rtion of a proximately 20. pounds of sulp ur 10 ga ons of par'afiin' oil in the proportion of from 1. to 2 gallons of,

gallons of lardoil. In testimony whereoL-I have signed my. name to this specification,
